SURVEY OF QUALITY OF SERVICES TO IMPROVE PERFORMANCE OF ROUTING IN MANET
Abstract

Author(s): Raju Sujane, Prof. Sumit Sharma

Ad hoc Networks (MANETs) make them highly desirable for the present day multimedia communications. Traditional routing protocols may not suffice for real time communications it depends upon the condi tions and our requirements. Though there has been considerable research in this area. MANETs are being used in numerous application domains from emergency rescue and relief to networks. To support real-time communications (such as audio and video) over MANETs, new Quality of Service (QoS) provisioning mechanisms need to be developed. There are many challenges in QoS provisioning for MANETs such as dynamically changing topology, wireless capacity limitations, heterogeneous network environment, limited battery power etc. Previous QoS surveys in MANET have only looked at QoS provisioning models, signaling and routing. This paper presents a complete survey of the challenges and current state of the art of MANET QoS Routing. We include a thorough overview of QoS routing metrics, resources, and factors affecting performance and classify the protocols found in the respective topics. Keywords: MANET, routing, QoS, challenges.
